DOORLOCK This invention relates to door locks and more particularly tosuch locks employed 111 single door or double door house cars.

In the application of the usual lock, hasp and hasp fastener to cardoors it is the cusand frequently all of the tolerance is absorbedtherein so that in use it becomes necessary to hammer the hasp over thestaple to effect locking of the doors. Under this condition,

as well as under a normal application of the door and lock, movementbetween the hasp and staple occurs responsive to the movement of thedoor when the car is in transit. The hasp and staple are, consequently,subjected to an incessant pounding producing considerable stress andwear in these parts and final failure thereof. Concentrated stresses andaggravated wear of the parts of the old door locks result, furthermore,from the relatively small contacting surface upon which such stressesand wear are incident. The use by the railroads, moreover, of

more rigid door and car constructions presents a situation where thestresses above mentioned must be carried by the various elements of thelock mechanism and cannot be absorbed by the door or car.

It is an object of this invention to provide a door lock which willnegative within the limits of the lock the effects of the discrepanciesof application. In the accomplish ment of this object the lock is soconstructed that any tolerance or. slack of the parts is automaticallyabsorbed.

. An object, furthermore, is the provision of increased area of bearingsurface between the lock parts so as to avoid a concentration ofstresses and to effect a reduction of wear.

A further object is the provision of a door lock in which direct bearingbetween'the pin and the hasp is effected, the pin being responsive tothe movement of the hasp to restore bearing therewithin the event ofmovement of the door.

It is an object, as well, to provide a door lock comprising a lock plateand a 'hasp of novel construction and interchangeable with I i thecustomary lock plate and hasp.

Other objects of' the invention'as well as advantages thereof willbecome apparent as the specification proceeds, the invention be-' ingillustrated in :the accompanyi d I ings forming a part of said sp ifi?vv I In said drawings I Figure 1 is a fragmentary elevation showing thelock of the invention" applied to a double door construction, the lockbeing shown in operative position.

The lock structure" of the invention is shown applied intheembodimentsillustrat ed, to a double door car construction; It isevident, however, that the lockis not limited to this particularapplication but that it may as readily 'be utilized in connection with"a single door car construction.'

In the application disclosed, the haspfastener 10 is securedto themaindoor 11 of i a double door construction, bymeans of rivets 12 extendingthrough the hasp fastener,

the door and thebacking plate 13. The door 11 is illustrated asacorrugated metallic door,

although it is evidentthat the lock may be 14 provided ad acent 390'applied to any type of door. Carried by the hasp fastener in the usualmanner is a'hasp, its free end with alug 15, the function of which ishereinafter set 5 forth. I

Secured to the customarily termed a uxil iary door 16 of the double doorconstruction is a lock member 17. This securement is effected by meansofrivets 18 extending through the lock member, the door and the backingplate 19. The construction of the auxiliary door illustrated forms nopart of The lock member of the lock construction is provided with twovertically spaced housing portions, 24 and 25, adapted to receive afastening pin 26. The portionof the-lock member betweenthe two housingsis plane as indicated at 27, and is adapted to receive the hasp when thelatter is in operative position. Each-of the housings 24 and 25 is provided adjacent one corner thereof with projections 28 and 29, theseprojections defining.

corresponding offset portions 28 and 29', respectively. The offsetportion 29' formed in the lower housing 25 extends for the depth of thehousing as indicated in Figure 6 of the drawings. The offset portion 28,as clearly illustrated in Figure 6, extends from the bottom of housing24 to a point below the top of said housing and thus provides a shoulderS for a purpose hereinafter described when the latter has been securedin "position. The provision of the offset portions 28' and 29 permitsthe formation of alug 30 on the lower end of the fastening pin 26 whilepreventing inadvertent hooking of saidlug on the lower portion of thehousings inthe retracting movement of said pin. Moreover, the offsetportion in the upper housing enables the pin, in its substantiallyretracted position, to assume an inclination toward the door to sustainthe pin in said position. Complete disengagement of the pin from theupper housing in the operative position of the lock plate 17 is avoidedby the shoulder S. The projections 28 and 29 serve to limit lateraldisplacement of the pin in its vertical movement. The lower housing 25is provided with'an opening 31, adapted to coact with an inclined slot32 formed in the lower portion of the pin to receive a sealing ribbonfor sealing the door.

The pin 26 is provided with one inclined edge, the opposite. edge ofsaid pin being straight and forming an abutment for the lug 15 of thehasp when the hasp and pin are in their operative positions. It is notedthat the inclined edge of the pin in its operative position is inengagement with similarly inclined portions of said housings. It isevident that by such an arrangement the stresses upon the lock aredistributed over a large area.

The operation of the lock structure is clearly illustrated in Figures 3and 4 of the drawings, and taken together with the de within thehousings of the lock member. 1

During the movement of the car a corresponding movement may be impartedto the door, whereupon said door will take the position indicated in dotand dash lines in F igures 3 and 4. It is clear from the drawings that,should the door remain at all times in the full line positionshown, thehasp will bear tightly against the pin and all relative movement betweenthe pin and hasp will be avoided. However, in the event that the doormoves from the full line position to the position indicated by the dotand dash lines it is evident that the hasp will have imparted to it acorresponding movement. The pin is thereupon released from therestraining influence of the hasp and, due to the inclined .edgethereof, will readily be lowered by the action of gravity until thecontacting relationship between the lug on the hasp and the pin.is againobtained. In this position, as well as in the former position, it is evident that noplay between the hasp and the pin is permitted. It isobvious, therefore, that with the elimination of the relative movementor play between the hasp and the pin all pounding between these parts isavoided.

In the embodiment of the invention shown in Figures 1 to 4, inclusive,and Figure 6, the hasp is illustrated as bein solid. In themodification'illustrated in igure 5 of the drawings, however, the lockmember 17, is provided with a laterally extending lug 33, adapted to bepositioned within a slot 34, provided in the hasp 35. As shown in Figure5, considerable clearance is provided between the lug and the walls ofthe slot and the lug terminates within the slot. In this construction aswell as that shown in the previous embodiment of the invention, atapered pin is employed and the function and advantages of said firstembodiment are maintained. In addition thereto, the modifiedconstruction of Figure 5 permits interchangeability where a latch of theconstruction shown is not available, by the use'of the old style hasp.In such a hasp, of course, the lug 15 is not provided, and while the pinand lock member shown may be utilized with such old style hasp it mustbe borne in mind that the cooperation between the tapered pin and thehasp provided with a lug is not obtained. However, the constructionpermitting the use of the old type hasp is effective and desirable forinterchangeability, inasmuch as it avoids undesirable bad ordering ofthe car and retention of the car in ,uninterrupted service. It isapparent, furthermore, that the hasp 35 and the tapered. fastening pin26 may be utilized with the usual lock member which embodies thecustomary lug provided with an opening through which the pin is adaptedto extend. With this usual lock member the tolerance between the haspand staple may not be absorbed but complete interchangeability isObtained for the purpose set out above.

Many modifications and changes in the structural details of theinvention set forth may obviously be made without departing from thespirit of the invention. All such modifications and changes are deemedto be comprehended in the invention which is to be limited only by thescope of the claims appended hereto.
